ing like parts,

My present invention relates to garage.

lighting fixtures, and more particularly to a portable electric lighting fixture adapted for universal adjustment.

Adjustable portable lightingfixtures have been devised in many styles and shapes, and yet all such fixtures that are at all practical havetheir field of usefulnessso limited as to be adapted to but few purposes. The limitations of adjustable. portable lighting fixtures have been sharply brought out with theadvent of the automobile, the necessary repairing of. which has brought a demand for a sturdy, portable garage light or fixture capable of a wide range of adjustment; The repair man cannotwbe bothered with, a fixture that takes the orwportion. of his time to adjust. One moment he must be working underthe machine and 1. the. next moment working on the top of the engine. Under present conditions he cannot do effective work as he has to continually adjust or even to hold the lighting fixture. No fixture in use at the present time. so far as I am aware, is capable of being adjusted through such a wide range as that indicated above as necessary.

In my copending application, Serial No. 319.044, filed March 23, 1918, I have described and claimed an adjustable flexible armoured bracket for use in shops, oflices, and the like, which bracket is capable of a wide range of adjustment. The limitations of such bracket however, prevent it from being an eflicient garage light other than as a wall or ceiling fixture. With a view to overcoming the objections to the present types of portable adjustable garage lighting fixtures and with a view to producing a practical garage fixture of this type, I have devised the subject matter of the present invention.

The principal object of my invention therefore, is an improved form of adjustable portable garage light.

Another object is an improved garage light cap able of adjustment through a wide range, both as regards vertical and horizontal adjustment.

Still another object is an improved garage light that is capable of readily being dismounted or dismantled for storage or shipment.

Other objects and novel features of the construction and arrangement of parts constituting my improved garage light will ap pear as the description of the invention progresses.

In the accompanying drawings illustrating the preferred embodiment of my invention,

Fig. 1 is an elevation showing the lighting fixture in its highest adjusted position,

Fig. 2 is an elevation showing the lighting fixture in its lowest adjusted position.

Fig. 3 is a plan View: showing the details of constructionof the base, and

liig. 4 is a central longitudinal section through my improved double universal joint.

Referring to the drawings, 10 designates a base composedo'f a tube 11, bent as shown in Figs. 1, 2 and 3, this tube 11 being joined toa tube 12. bent to. the form showmthe tubes 11 and 12 beingconnected together by the members 13 and 14, straps 15 and nuts 16. This form of construction makes a tripod base that is easily, economically, and rapidly assembled and disassembled and one in which th centre of gravity is exceedingly low.

Intermediate the ends of the tube 12 is a second clamp identical in construction with the clamp above described, and this clamp is utilized to rigidly, and removably, hold the short length of tube 17 to the tube 12. This tube 17 may be of any length desired, but I prefer to have it not over seven inches in length in order to support at its upper end large bevelled end 18, a double universal joint comprising the half body portions 19 and 20, each provided with a central hollow depression 21 and with a hemispherical depression 22 at each end. Bolt holes 23 are also provided, through which pass bolts 24 provided with nuts 25 for clamping th half body portions together to form the universal joint. Split ball members 26 are situated in the depressions 22, as clearly shown in Fig. 1, each of such members 26 being provided with circumferential grooves 27 to receive the enlarged bevelled upper. end of the short tube 17 and. also the enlarged lower end 28 of a tube 29, this tube 29 being of any convenient length and also bent at 30, near its lower end, in order that the major portion of the length of the tube may be forced into a position substantially parallel to the ground or floor, as shown in Fig. 2, and also substantially vertical to the ground or floor, as shown in Figs. 1, and A, it being noted in Fig. 4: that the members 26 may be rotated in the depressions 22 to position the tubes 17 and 29 in any position relative to each other and to the universal joint,-the degree of freedom of such movement in the universal joint being adjusted by means of the bolts 24 and nuts 25. Attached to the upper or free end of the tube 29, by an improved threadless pipe coupling 31, which forms the subject matter of my Patent No. 1,505,077, dated Aug. 12, 1924, is a flexible armoured cable 32, of suitable length, this armoured cable being rendered capable of retaining any position into which it may be put, while yet retaining its flexible character, by a reinforcing wire or rod 33 attached to the cable by binding wire 84. Attached to the other end of the flexible armoured cable 32 by a threadless pipe coupling 35, is an ordinary lamp socket 36 and reflector 37.

From the above description, it is obvious that my improved garage light or fixture is portable, may be readily assembled or disassembled, and may be adjusted to any position through 360 and at any height from the lowermost position shown in Fig. 2 to the highest position shown in Fig. 1. The range of adjustment of my improved lightwithout disturbing the relation of the armoured cable to the rigid arm or tube 29.

My improved garage light is not, ot course, limited in its application to garages, but may be used in any position where a portable light is required.

IVhile I have described the preferred embodiment of my invention somewhat in detail, it is to be understood that I may vary the size, shape and arrangements of parts constituting my device within wide limits without departing from the spirit of the invention.

Having thus described my invention, what I claim as new, is

A portable adjustable lighting fixture comprising a demountable base, a supporting pipe mounted thereon, a curved rigid arm, a universal jointinterposed between said pipe and said arm and connecting the arm to the base for movement in any direc- 7 tion with respect thereto, and a. flexible light carrying cable attached to the rigid arm and movable with respect to both the base and rigid arm.

In testimony whereof, I have signed my name to this specification.
